In all fairness that is the 820 and the E5-2660s. I think the 620 with E5-2650's is most likely the better comparable to what we'll see available with the Mac Pro. That will probably drop the price by at least $1000, but I can't seem to get back to the configure page on hp's website right now.

I agree that the 620 with E5-2650's is most likely the better comparator to what we'd see available with the Mac Pro, if Apple did choose or has chosen to continue producing the 2P Mac Pro. However, would Apple be able to sell dualies with two E5-2650 2.0 GHz -> Turbo 1 - 2.4 GHz -> Turbo - 2.8 GHz [(8 bins/steps) 8/16-cores 8GT/s-QPI] at that price and meet our performance expectations and their sales expectations? I doubt it. We'll grow to cherish those old Westmere days, just as some now cherish those much more reasonably priced high end Mac Pros of 2008 (when for < $4K you could buy the top of the 2P line). Thanks be to greed and Intel for relieving us of that joy.

There was but it was a dual processor dual core.

Xeons are capable of being used in 4 processor configurations for 24 physical cores and 48 logical cores (on Westmere.) Those are waters that Apple has never waded into.

There are even 8P (80-core or 128-core) and 12P (96-core) [ http://browse.geekbench.ca/geekbench2/top ] systems that you can buy at Cadillac/Mercedes prices. Smartly, Apple has avoided them.

-----------

I think the sweet spot price/performance-wise (in a dually) will be one of the dual hex-core setups. At least that's what I may build if the Mac Pro line is kaput. 12 cores with 32 gigs of RAM and a good video card bolted to an EVGA SRX. And the Enermax FulmoII case which has no problem fitting the HPTX form factor....

Too true.

ok so...........yet ANOTHER pc vendor builds yet ANOTHER high-end tower with all the latest & greatest gizmos, and hypes it up on it's website as the best thing since sliced bread........... d U h

Can someone p u h l e e z explain to me just exactly how this is different or news ????

It's probably because HP is the number one computer seller in the US and makes some of the most respected workstations in the business. For example, Sony uses HP workstations with their professional broadcasting/editing software suite.

----------

I don't understand what is so sweet about that case. Both inside and out it looks like every other generic black PC case.

At least it doesn't have a window and lots of lights. That's pretty sweet in the windows world. ;)
 
If you look very closely at the prices HP intends to fetch for the dualies, this may help explain why you haven't heard a peep from Apple (and may never hear that peep). $7,000+ for a dual E5-2660 [each 2.2 GHz -> 2.6 GHz -> 3.0 GHz (8 bins/steps) 8/16-cores 8GT/s-QPI] system with just 16 gigs of ram and a crappy video card. Sure, Apple has sold comparable systems for less than HP and Dell, but not for so much less as to cause dual 8-core 2.2 GHz systems to start flying out of the warehouse in exchange for over $6K. Even HP is still making Westmere systems, because dual Sandy Bridge E5s will be priced mainly for corporate/university users. I suspect that Ivy Bridge dualies will follow suit, priced mainly for the 1%.

I still think that hardware wise, the macpro is more comparable to the 420 series than the 820 series. 7K is insane, but you have more ram support, more HD bays, SAS Raid, right?

----------

I've been following the MP future threads and have also been wondering what else might be available. I dont have any issue with HP and they do make some good products but I do like business ThinkPads as they are quite durable. I know this is an HP workstation thread but I wonder how they compare to the ThinkStations

http://shop.lenovo.com/SEUILibrary/...79A8343A4425A902C65DD0D45C75&tabname=Overview

I love Lenovo, that's option #2 if I don't go with the HP one. But now that the HP's have USB3, they are up in front.

I do not disagree. I would certainly prefer the 2660s when buying a workstation that is going to cost ~$6K once completely outfitted. The extra $200 per processor to go from the 2650 to 2660 seems worth it to me. That would be $2600 just for the processors, add in about $1000 for MoBo (especially since its probably still going to have 8 DIMMs) and case, maybe $500 for the video card, and there really should be plenty of dollars left for the profit margin, cheaper components and overhead.
 
Once the new Xeons ship, what's the point of keeping the Mac Pro around? No one will buy it at those prices, and Apple has to dedicate manufacturing and shipping resources on it.

There are several reasons. First, some people will buy at those prices. Some people are not going to dump their entire software and infrastructure stack and actually use the machines to generate revenue at high mulitples to the machine's cost. [ For many shops I'd suspect the user using the Mac Pro is a higher cost and impediment to generating profit than the Mac Pro is. If not generating enough money to pay for the Mac Pro itself then there are deeper business problems than selection of Mac OS X based solution. ]

Second, Apple has no manufacturing. They outsource it. As long as the contract outsource can fire up the line and produce, say 2,000 a month, they'll probably agree to it. Apple can either be filling the gap until new model is released ( vendor should be quite happy to get that work too as highly likely 'bridge' work to keep them busy in the mean time ) or letting the Mac Pro slowly coast to a halt. Slamming on the breaks does what??? As folks keep pointing out the Mac Pro is highly profitable per unit. The R&D on the current model is probably already paid for. There is just component costs and the bill for putting it together which the price more than covers.

If the Mac Pro isn't cut by the time other makers start shipping in volume, it's doubtful Apple is going to abandon towers.

That has very dubious causality. For example, Apple didn't kill the XRaid on a technology boundary ( like better RAID controllers or moving to SATA II ). Likewise, the XServe was not retired on a technology boundary for Xeons or in the immediate context of a large number of competitive 1U server model upgrades. The 30" Display was on the market for how many year before it just dropped out of the pure display market? It too slow stopped to a halt. (Apple's "Displays" have slowing mutated into docking stations with embedded LCDs)


If you are posing this as Apple has to wait for another Mac model to arrive before replacement. That is not necessarily true it is a tower.
As likely Apple could:

Dump all towers in exchange for expanding the MBA line (MBA 15" ) .

Dump all towers in exchange for a "HP Z1" like "super" iMac.

If Apple doesn't think the tower market is viable and therefore cancel the Mac Pro then there doesn't have to be a replacement.

If Apple thinks the tower market is viable then there will be a follow on Mac Pro.

But the lack of a cancellation doesn't really send any informative light as to which one of those beliefs they hold. It didn't for XServe or XRaid.


I don't think Apple unilaterally wants to exit the tower market. If there aren't enough folks buying Mac Pros, not sure what their competitors do is suggestive at all as to what Apple is going to do. For example, when many of their competitors piled into netbooks, Apple didn't slavishly follow. (the MBA 11" is as low as they did the limbo to. That wiped out the MacBook, but that is a fast growth subsegment market not a plateauing one. It is the entry laptop price point.) Their competitors also internally cannibalize they own units with highly overlapping product lines (e..g, discount small boxes/towers vs. all-in-ones ).


The only reason to keep it around at that point is to cleanly transition to a new machine.

They could also transition to retirement of the category too.

In May/June 2010, there were some predicting doom for the Mac Pro too. ... and another model came in July/August. Intel's, HP's, Dell's, and Lenovo doesn't always dictate when Apple makes its moves. There was no good reason to "hurry up" in 2010 to drop a new Mac Pro since there was a "2 year" gap in Intel's release coming. If Apple is looking at another projected/predicted large gap for Intel to rev past the Sandy Bridge E5's there is no hurry now either. However, it is also likely that all the R&D for the Sandy Bridge Mac Pro is already done.... so they might as well ship if they think it is a viable market once all the major parts are ready for volume production.
 
I still think that hardware wise, the macpro is more comparable to the 420 series than the 820 series.

You mean the 420's that have:
greater than 3 drive sleds
dual GbE sockets
ability to host multiple E5 processors


the Mac Pro is aimed more between the 620 and 820. There is a different emphasis one DIMMs slots in the Mac Pro internally than those two, but it s more aligned with those than the 420.

There is some small strife in the Mac Pro market because one sub-segment of the market would choose to dump dual Xeon and higher power requirements for lower costs. ( just make E5 1600 series boxes). The other subsegment thinks dumping the single package model would bolster the case for "bigger iron" inside the box (dumping the RAM/CPU tray for more fixed internal bulk).

Having a Mac Pro that straddles those to opposing directions is better than having no Mac Pro at all.
 
There are even 8P (80-core or 128-core) and 12P (96-core) [ http://browse.geekbench.ca/geekbench2/top ] systems that you can buy at Cadillac/Mercedes prices. Smartly, Apple has avoided them.

In a year or so that won't be all that hard to do if just need cores to crunch numbers:

"... the "Knights Corner" co-processor that is capable of delivering more than 1 TFLOPs of double precision floating point performance. ... "
http://www.tomshardware.com/news/intel-knights-corner-mic-co-processor,14002.html

"... The first supercomputer powered by the KNC will be, as planned, turned on in 2013. ..."
http://www.xbitlabs.com/news/other/...er_MIC_Supercomputer_Chip_In_Great_Shape.html

"...it's likely that TDP is likely to be in the GPU-like 200 to 275 watt range ... "
http://www.hpcwire.com/hpcwire/2011...ark_of_one_teraflop_with_knights_corner_.html

The only stumbling issues for a Mac Pro would be the card draws too much power (in the 275W range ) or that there were no drivers to interface with the on-board OS/hardware (likely just Linux drivers) . Remains to be seen if the pricing is going to be in the Cadillac/Mercedes zone.
 
There are several reasons. First, some people will buy at those prices. Some people are not going to dump their entire software and infrastructure stack and actually use the machines to generate revenue at high mulitples to the machine's cost. [ For many shops I'd suspect the user using the Mac Pro is a higher cost and impediment to generating profit than the Mac Pro is. If not generating enough money to pay for the Mac Pro itself then there are deeper business problems than selection of Mac OS X based solution. ]

Sure. Some people buy 4 and 8 processor machines. Just because some people would buy it doesn't mean enough people would buy it.

Like I said, for years Apple didn't compete against the Xeons and pros were ok. And if Apple wants to go for the "fastest workstations" title, they've already lost against the 4 processors.

Second, Apple has no manufacturing. They outsource it. As long as the contract outsource can fire up the line and produce, say 2,000 a month, they'll probably agree to it. Apple can either be filling the gap until new model is released ( vendor should be quite happy to get that work too as highly likely 'bridge' work to keep them busy in the mean time ) or letting the Mac Pro slowly coast to a halt. Slamming on the breaks does what??? As folks keep pointing out the Mac Pro is highly profitable per unit. The R&D on the current model is probably already paid for. There is just component costs and the bill for putting it together which the price more than covers.

True, but can they keep selling Mac Pros at a $7k price point? Again, I'm not denying that they can make them or that they can manufacture them. I'm just saying, at the rising price points they're going to end up driving people to the iMacs.

That has very dubious causality. For example, Apple didn't kill the XRaid on a technology boundary ( like better RAID controllers or moving to SATA II ). Likewise, the XServe was not retired on a technology boundary for Xeons or in the immediate context of a large number of competitive 1U server model upgrades. The 30" Display was on the market for how many year before it just dropped out of the pure display market? It too slow stopped to a halt. (Apple's "Displays" have slowing mutated into docking stations with embedded LCDs)

Yeah, but the XServe served to a niche. If you needed a rack mounted Mac OS X server, XServe was the only way to go. You didn't really care if the processor was a bit old. (Not to mention the processor wasn't almost two years old.)

The Mac Pro? Unless you're a FCPX editor, there are other options.

If you are posing this as Apple has to wait for another Mac model to arrive before replacement. That is not necessarily true it is a tower.

If Apple thinks the tower market is viable then there will be a follow on Mac Pro.

I don't think (at least I'm hoping) that Apple will exit the tower market. I just think they may ditch the Xeons for the towers and move to i7s. It really depends. If a large majority of the Mac Pros they sell are single processor, it's going to be a no brainer. No reason to inflate the prices for the majority over the Xeon.

Still the points you've listed above are reasons that I think if Apple was going to kill their tower line they would have done it already. The replacements are already in place if they want to get out of towers. Nothing to wait on.

But the lack of a cancellation doesn't really send any informative light as to which one of those beliefs they hold. It didn't for XServe or XRaid.

If we're going to bring XRaid into this... That was a little different. Apple had Mac compatible third party hardware at the ready, and the XRaid software was still produced.

I don't think Apple unilaterally wants to exit the tower market. If there aren't enough folks buying Mac Pros, not sure what their competitors do is suggestive at all as to what Apple is going to do. For example, when many of their competitors piled into netbooks, Apple didn't slavishly follow. (the MBA 11" is as low as they did the limbo to.

Their competitors also internally cannibalize they own units with highly overlapping product lines (e..g, discount small boxes/towers vs. all-in-ones ).

I agree, but I just don't think using the Xeon is sustainable at this point.

If you look at the real big target markets for the Xeon like rendering clusters, servers, and cluster computing, those are all markets Apple is abandoning. FCPX (which I don't think Apple is abandoning) would run great on 12 or 16 cores, but with the GPU optimizations being done you could probably get away with 8 cores, and a high end GPU, and still have a really good experience.

GPUs are a big reason Apple needs to keep the towers though. People can tell me all day how fast their 4 core iMacs are, but it doesn't matter as long as they don't have desktop GPUs. Not that 4 cores is all that fast anyway.


In May/June 2010, there were some predicting doom for the Mac Pro too. ... and another model came in July/August. Intel's, HP's, Dell's, and Lenovo doesn't always dictate when Apple makes its moves.

Oh yeah, we go through this every year. And I'd feel like this whole thing was overblown except for things I've personally heard. (Disclaimer: I know nothing solid about the future of the Mac Pro.)
 
There is some small strife in the Mac Pro market because one sub-segment of the market would choose to dump dual Xeon and higher power requirements for lower costs. ( just make E5 1600 series boxes). The other subsegment thinks dumping the single package model would bolster the case for "bigger iron" inside the box (dumping the RAM/CPU tray for more fixed internal bulk).

I certainly see both sides of that argument. Its a little annoying to have a DP mobo and be limited to 8 DIMMs, but if the OS is only going to recognize less then or equal to 128 GB of RAM anyway, it doesn't really matter. Anyway, my point being, the sacrifices they are making on the DP front are much worse than those on the SP front.

Now with the Xeons bolstering 8 cores on a single chip, it might not be a terribly bad idea to just go with a single processor model. If Apple added options for say the 2660 and the 2680, then they could appease those that want high power at least some. They could also still add some DIMMs and manage to make the case a little smaller. As long as they had 6 DIMMs, you can relatively cheaply get to the 96 GB RAM limit on OSX anyway. So, why have more?

But then if they do that, they will be left in the awkward situation that the 2010 12-cores are faster machines...

I hope that the Knights Corner systems will be substantially less than the pricing in the Cadillac/Mercedes zone.

This is but one example of what I meant by stating,"There are even 8P (80-core or 128-core) and 12P (96-core) [ http://browse.geekbench.ca/geekbench2/top ] systems that you can buy at Cadillac/Mercedes prices. As to the 8 CPU 128 core system that has

(2) 258329 gigs of ram [ http://www.superbiiz.com/detail.php?name=D3-13R16GH ], and

I drew my comparison based on the following:

(1) CPU - $3692 x 8 = $29,536
(2) Ram - assumed using 16 16-gig chips = 16 x $185 = $2,960
(3) Supermicro (X8OBN-F) case, mobo, onboard video, but without any storage: List Price: $27,627.76 On Sale: $10,360.51 and compared $29,536 + $2,960 + $10,360.51 = $42856.51 (w/o any OS or storage to install it to) with

(1) 2012 Cadillac SRXMSRP: $35,985 - $49,585
Base Sport Utility $35,985
Luxury Collection Sport Utility $40,515

(2) C-Class Mercedes' entry-luxury sedan and coupe $34,800 - $61,430 [ http://autos.msn.com/browse/Mercedes-Benz.aspx ].

This 8-core system's price estimate is probably on the low side because, in addition to leaving out storage and OS cost, it involves one doing some of the install/labor him/herself. The Cadillac and Mercedes probably shouldn't have that much buyer labor involved to get it running. I would also suspect that buying a fully configured 8 core system would cost more than indicated above and that the 12 CPU system probably costs even more. But to get one 8 CPU system that benches only about 18% faster than my 2P system for over 7 times the cost of mine, I personally would find hard to justify. I believe that this is part of the reason why Intel has locked down the Sandy Bridge Xeons from tweakers.

Anyway, my point being, the sacrifices they are making on the DP front are much worse than those on the SP front.

But the DP side is smaller. Let's say 65% of Mac Pro buyers are single package ( making 35% dual package). That's might be OK if Mac Pro's represented say 10% of all Macs sold. It present a problem if Mac Pro's represent 1% of all Macs sold. Loose that 35% and drop below single digit percentages. That would likely get both variants canceled. If snared 60% of that ( still not at 0.86% ). There would have to be some kind of significant inflection where the number of singles shot up over what they were to both make up the lost ground and expand the base that was already there.

If it is a 50-50 split it is even harder to make up the ground. If it is a 80-20 (single:dual) split then it is much easier.

My suspicion is that it is a small enough percentage to not tip the design decisions into its favor, but large enough so that if dropped would create a significant hole. Hence, the compromise. If Apple could build two separate boxes, segment them on price , and sell both a high single digit percentages I suspect they'd already be doing that.


Now with the Xeons bolstering 8 cores on a single chip, it might not be a terribly bad idea to just go with a single processor model.

One problem though is that if people have software that productively adds value because it can scale from 4 to 8 cores, then it probably also gives a boost going from 4 to 10-12 cores. Well design codes could easily give a boost if go up to 16. Apple would be leaving money on the table they don't have those options because they can charge more for that added value.



If Apple added options for say the 2660 and the 2680, then they could appease those that want high power at least some. They could also still add some DIMMs and manage to make the case a little smaller. As long as they had 6 DIMMs, you can relatively cheaply get to the 96 GB RAM limit on OSX anyway. So, why have more?

Once 96GB of RAM is reasonably affordable Apple is probably going to boost that limit. At that point, the single package with 4 controllers becomes a limit. It hasn't been relatively cheap to stuff 96GB into a box until relatively recently (like after 2008-2009 when the Mac Pro DIMMs design constraints were baked in.)


"8 cores and 96GB should be good enough for everybody" seems alot like "640K should be good enough for everybody". I don't think 32+GB is common but it not as rare as it once was.


But then if they do that, they will be left in the awkward situation that the 2010 12-cores are faster machines...

Only on workloads that scale. For the workloads that have huge serial computation constraints is plays into the hands of the folks who just put high value on high max turbo GHz.

However, it is also not just the 2010 box. You can also build a dual 2630 for less money ( 2 * 612 -> 1224) for less than a 2670 ($1552) and dual 2640 ( 2 * $885 -> $1,770 ) for almost same price as 2680 ($1723). That extremely likely means that competitors will be undercutting the Mac Pro price (especially after Apple tacks on the 30% mark-up). Those loose on serial code that requires turbo since they can crank as high, but


I think the bigger issue is whether top end computation is going to be driven from the x86 sockets or PCI-e slots. If it is PCI-e slots ( plug-in TFlops) then having two E5's is better. PCI-e lane constraint will be a bigger issue than DIMM slots. With more CPU packages come more lanes.

....
systems that you can buy at Cadillac/Mercedes prices. As to the 8 CPU 128 core system that has
...
(1) 2012 Cadillac SRXMSRP: $35,985 - $49,585

Not likely. There are Nvidia 6GB Telsa cards (m2090) in the $3-4K range. There are versions available for less. I don't think folks will buy very many $30K cards to put in $3K boxes. The ratio is just too skewed. Intel may try to put price premium on their card, but by that time there will be competing AMD and Nvidia cards with similar performance that help keep that from getting outrageous.


The interesting turn is that that the 50 core card will likely be in the same price range as the current top end Mac Pro once mated with an entry level Mac Pro. The huge impediment would be just software that fully leverage that augmented entry level system.

Those $30-40K systems are far more optimized for running substantially different computational workloads. I have no idea why folks would geekbench such as system other than just for giggles.. That is a pretty poor benchmark for what they are good at.
 
Sure. Some people buy 4 and 8 processor machines. Just because some people would buy it doesn't mean enough people would buy it.
.....
True, but can they keep selling Mac Pros at a $7k price point? Again, I'm not denying that they can make them or that they can manufacture them. I'm just saying, at the rising price points they're going to end up driving people to the iMacs.

You mixing up two different issues. One is "enough folks" to continue selling a product you have already recouped investment on and "enough folks" to continue R&D (make new investments), do major upgrade , and/or introduce brand new product.

It is much easier to coast along with an mature product. Likewise it is much cheaper to sell only into your installed based looking to replace vintage and/or obsolete equipment over the near term future.

It isn't the the $7K price point. The iMac only has high traction on the single package models and those top out at $3,700. Maybe $4-5K with some reasonable options from Apple.

The $7K market would overwhelmingly head for Windows instead of an iMac. Apple getting by on Mac Pro sales for the next 4-6 months would likely be about as hard as it was for them to get by on sales for the last 4-6 months. Sure there are "newer" models for those who wish to bolt now. But the option to bolt existed 4-6 months ago also.


Still the points you've listed above are reasons that I think if Apple was going to kill their tower line they would have done it already. The replacements are already in place if they want to get out of towers. Nothing to wait on.

There is no MBA 15" Mac. Neither is there a Z1 like Mac. The Z1 is twice as thick as the iMac. A workstation iMac would be as different from the current iMacs as the MBA 11" is from the MBP 17". Yeah they have both have LCD screens but there is a substantive difference in thinness design constraints.

Since they don't exist .... they could wait for release.

If the replacements were already in place (something they had 100% control of and were already done) they could have pulled the trigger before now... not wait until exactly when their competitors move.

However, yes. If boxes that hold 150-250W PCI-e cards are a viable market then the Mac Pro likely will continue. One of the issues is that all the possible suitable cards of that nature haven't shipped yet. After they do and after the major system competitors ship you can start a "countdown clock" upon when Apple would 'have to' cancel the Mac Pro. Right now is actually a bad time.

deconstruct60,
Thanks for triggering the firing of recently dormant mental neurons and tickling the associated ganglia. There's a burden to showing that you really deeply know your stuff --> it is that people, like me, want to pick your brain. So here goes. Would I be correct in assuming that you believe that Knights Corner (KC) or 50-core cards will overshadow the market for high end compute performance or at least put downward pressure on the price of Nvidia's Cuda/Tesla cards (because of the seemingly easier adaptation of KC to the task at hand and greater performance) and do the same on GP MP Xeons? My principle need for speed is required for 3d and video rendering. Are you aware of whether any 3d software or video editing software companies that have mentioned KC or 50-core card's having an impact on their future direction? How many KC or 50-core card cards do you believe could be placed in a 1P vs. 2P vs. 4P vs. 8P vs. 12P system and what variables do you believe that I should take into account on my next motherboard purchase? What kind of PSU and cooling requirements should I be planning for to take greatest advantage of KC or 50-core cards next year? Would I be correct in also assuming that you would recommend just using one GP GPU and saving the other slots for KC or 50-core card if the software that I use can take advantage of them?

The interesting turn is that that the 50 core card will likely be in the same price range as the current top end Mac Pro once mated with an entry level Mac Pro. The huge impediment would be just software that fully leverage that augmented entry level system.

Does this mean that it's your belief that each KC or 50-core card will be priced in the $3-4K range; if not, what range for each? Will either card run on Westmere systems?

deconstruct60 said:
Those $30-40K systems are far more optimized for running substantially different computational workloads. I have no idea why folks would geekbench such as system other than just for giggles.. That is a pretty poor benchmark for what they are good at.

What will such systems still be good and cost effective for after KC or 50-core card's arrival? This information will improve my understanding of what you see as MP's and KC or 50-core card's precise limitations and advantages.

Thanks, again.

But the DP side is smaller. Let's say 65% of Mac Pro buyers are single package ( making 35% dual package). That's might be OK if Mac Pro's represented say 10% of all Macs sold. It present a problem if Mac Pro's represent 1% of all Macs sold. Loose that 35% and drop below single digit percentages. That would likely get both variants canceled. If snared 60% of that ( still not at 0.86% ). There would have to be some kind of significant inflection where the number of singles shot up over what they were to both make up the lost ground and expand the base that was already there.

If it is a 50-50 split it is even harder to make up the ground. If it is a 80-20 (single:dual) split then it is much easier.

I'm not saying your necessarily wrong, but offering a more specialized selection could also bring in other customers that would otherwise not buy the current Mac Pro. All I was trying to say before is that the current format hinders the high end workstation user more than that of someone that wants the lower end. And you're probably right that by splitting the middle Apple is trying to draw a larger crowd. Which brings us to the next point...

My suspicion is that it is a small enough percentage to not tip the design decisions into its favor, but large enough so that if dropped would create a significant hole. Hence, the compromise. If Apple could build two separate boxes, segment them on price , and sell both a high single digit percentages I suspect they'd already be doing that.

Exactly, this is just information we don't have, but Apple probably puts significant market research into. So, their actions likely give us the "correct" choice, especially given their current success.

One problem though is that if people have software that productively adds value because it can scale from 4 to 8 cores, then it probably also gives a boost going from 4 to 10-12 cores. Well design codes could easily give a boost if go up to 16. Apple would be leaving money on the table they don't have those options because they can charge more for that added value.

Right, but the 6 core options will then be faster for those with tasks that don't scale well anyway. Thus, the 8 core is just an appeasement for those somewhere in the middle. Just like making a DP version with "only" 8 DIMMs, 4 HDD bays was as well. Its just the next step away from the high end user. Which, just for full clarity, I personally don't want to see. My work is extremely multithreaded in nature. And, usually the tasks that require one to only a few cores aren't that time intensive.

"8 cores and 96GB should be good enough for everybody" seems alot like "640K should be good enough for everybody". I don't think 32+GB is common but it not as rare as it once was.

I'm not trying to say its perfect, or for everyone, I'm just saying it could be a better market choice between the two camps given today's technology. Four years ago this wasn't really the case, but things might have changed for the Mac Pro.


However, it is also not just the 2010 box. You can also build a dual 2630 for less money ( 2 * 612 -> 1224) for less than a 2670 ($1552) and dual 2640 ( 2 * $885 -> $1,770 ) for almost same price as 2680 ($1723).

But with the dual sockets come the costs of more power consumption and dual processor boards, which mean that $300 savings between the processors for the 2x2630 and the 2650 is eaten away. It also means more space and/or more noise, and of course more electricity.

Plus there is the turbo range to consider. The 2670 will get to 3.3 the 2630 to 2.8 a 17% advantage for the 2670. And on the bottom end, the 2670 will operate 8 cores at 3.0, the 2630 6 at 2.6. So total with all active in with the 2670 vs 2*2630s gives the 2630 a 30% advantage. Its just the kind of thing that depends on your work flow. If you're mixing a lot of well threaded stuff with single threading things, a single 8 core that turbos above 3.0 looks pretty appealing.

That extremely likely means that competitors will be undercutting the Mac Pro price (especially after Apple tacks on the 30% mark-up). Those loose on serial code that requires turbo since they can crank as high, but I think the bigger issue is whether top end computation is going to be driven from the x86 sockets or PCI-e slots. If it is PCI-e slots ( plug-in TFlops) then having two E5's is better. PCI-e lane constraint will be a bigger issue than DIMM slots. With more CPU packages come more lanes.

That is certainly another issue, and is just something else Apple will have to balance going forward. It starts to get into where software goes with GPGPU computing and how much we begin to rely on 200+W GPUs for general purpose computing. This is something I have to admit a certain amount of ignorance on however. All I know is that only a small fraction of the scientific stuff I'm using only is just beginning to use GPGPU to accelerate some tasks. Given what I've seen though, and for the price of these Teslas, its just better use a cluster if need more than a workstation with 2 xeons.

You mixing up two different issues. One is "enough folks" to continue selling a product you have already recouped investment on and "enough folks" to continue R&D (make new investments), do major upgrade , and/or introduce brand new product.

That's not really how it works. The Mac Pro is a continuing investment. They have to market, they have to do software support, they have to stock it, they have to dedicate manufacturing resources for it.

You can't just make an initial investment and call the rest pure profit.

It is much easier to coast along with an mature product. Likewise it is much cheaper to sell only into your installed based looking to replace vintage and/or obsolete equipment over the near term future.

I kind of agree with this... The problem is I think the Mac Pro has hit a coasting wall. With Thunderbolt and Sandy Bridge, Apple has to make tough choices and can't coast.

In addition, there is a "why do we care?" attitude. Every engineer, qa person, software developer, and salesman supporting a $7k Mac Pro for a small audience is a person that could be elsewhere in the company. *cough*iOS*cough*iPhone*cough*iPad*cough*

Quite frankly, if the Mac Pro keeps loosing users, it's not sustainable. And if the price keeps pushing up, it's going to lose users.

The $7K market would overwhelmingly head for Windows instead of an iMac.

Understood. But the key question is: Does Apple care?

And again, I'm not suggesting Apple is going to dump the tower and shuffle everyone to an iMac. I'm questioning the continued existence of a DP tower, not the SP tower. But if Apple lost the users looking for a 12 core machine, is that going to really matter to them?

It's a matter of triage. Either you lose the lower end users who are mad about shifting Xeon prices and are going for i7 towers, or you lose 12 core users to Windows. Who do you think makes Apple more money?

Ideally they could do both an i7 tower and a DP Xeon tower but I just don't see that in the cards.

There is no MBA 15" Mac. Neither is there a Z1 like Mac. The Z1 is twice as thick as the iMac. A workstation iMac would be as different from the current iMacs as the MBA 11" is from the MBP 17". Yeah they have both have LCD screens but there is a substantive difference in thinness design constraints.

Since they don't exist .... they could wait for release.

If the replacements were already in place (something they had 100% control of and were already done) they could have pulled the trigger before now... not wait until exactly when their competitors move.

If Apple kills the Mac Pro and doesn't have a replacement tower, I don't think there is going to be a workstation iMac. The existing lines are going to be what we get.

However, yes. If boxes that hold 150-250W PCI-e cards are a viable market then the Mac Pro likely will continue. One of the issues is that all the possible suitable cards of that nature haven't shipped yet. After they do and after the major system competitors ship you can start a "countdown clock" upon when Apple would 'have to' cancel the Mac Pro. Right now is actually a bad time.

I think the Mac Pro market is a market Apple would like to continue to be a part of, but unlike HP, they built their entire tower market on the Xeon, and it's biting them in the ass. The reason pro towers are more sustainable for HP is because HP has more customization options. Lower end user who needs an i7? Yeah, they've got that. High end user who needs a few processors? They've got that too.

The Apple of today just doesn't have the attention span for that sort of multi tower market, profits aside. Something is going to give somewhere.
 
The Apple of today just doesn't have the attention span for that sort of multi tower market, profits aside. Something is going to give somewhere.

And its really too bad. Because many of things that run great on multi-processor systems are things you need Unix/Linux for. And OSX is in my opinion the far and away best Unix/Linux operating system.
 
Apparently I missed this but back in March HP announced their new workstations, and they just started shipping. So perhaps that means something is on the horizon for the mac pro?

Pretty sweet new version of their case and USB3! :)
http://h10010.www1.hp.com/wwpc/pscmisc/vac/us/product_pdfs/Z420_datasheet-highres.pdf

I use their 400 and 800 stations at work, I think I might buy a 420 for my apt.

Nice find, can you imagine if Apple releases the MP without USB 3? lol No way I'm spending that much money on a rig without the latest connectors. I'm looking at a new Sony camera coming out that has USB 3, also have thumb drives and some external drives that have USB 3, it's much faster than USB 2, making my job faster and easier. Sorry, but cameras, thumb drives, and cheap and simple external drives will not support thunderbolt so easily. So if anyone thinks USB 3 is not important and complimentary to Thunderbolt are kidding themselves.
 
Would I be correct in assuming that you believe that Knights Corner (KC) or 50-core cards will overshadow the market for high end compute performance or at least put downward pressure on the price of Nvidia's Cuda/Tesla cards (because of the seemingly easier adaptation of KC to the task at hand and greater performance)

I don't think it would put downward pressure on the Nvidia cards. Just that they are competitive and have significant overlap in utility. Windows PCs and Macs have pressures on each other to keep the prices from rising too high. They don't necessarily have pressures to minimize the prices. There is a big difference between those two.

It is going to be much easier to port x86 parallel code to this card though. It is kind of like having a 50 cpu linux cluster put onto a single PCI-e card. For those software vendors that have a linux port of their app arleady ( e.g., a batch job engine used in clusters) they basically just need to stick in a number of pragmas and recompile with Intel's compilers that can target the function units on these new cores ( the SIMD vector engine primarily).

Here's a presentation on the programming models for these MIC processors.

www.olcf.ornl.gov/wp.../ORNL_Elec_Struct_WS_02062012.pdf

In particular, slides 13 and 17. They outline how the MIC card could functional independently for some loads and how it is linked to host computer by a virtual network link.


It is not about knocking out the highest end number crunching. (at least not when used in a single workstation). It is more so about giving the workstation user access for an relatively affordable (no more than the workstation itself) , high speed connected ( likely faster than the external storage is connected and probably the internal storage ) , limited sized memory cluster inside the box.

Multiuser clusters have batch queues. Your relatively small job might only take 5 mins, but you could wait 75-360 minutes if that cluster is highly oversubscribed.







and do the same on GP MP Xeons?

No. The GP Xeons are there primarily to:

1. run the highly scalar limited jobs. ( the clock on these 50 cores is likely going to 1/3 to 1/4 that of the general purpose Xeons they are connected to)
***
2. manage the I/O with larger RAM , storage disks , and networks.

3. Manage the "Fork/Join" aspects. They will segment and tile the problems so that the MIC card(s) can handle the "embarrassingly parrallel" parts with their substantially faster, but limited, RAM resources. Chopping the problem into pieces means later having to put it back together again.





*** There may be some overlap in the new wide AVX ( SIMD) abilities in the newer Xeons and the vector units in these 50 cores over time but the MIC will simply dominate in sheer numbers. For jobs that require just a limited number of vector units ( 6-10) the Xeons will have more traction.





My principle need for speed is required for 3d and video rendering. Are you aware of whether any 3d software or video editing software companies that have mentioned KC or 50-core card's having an impact on their future direction?

This is a specialized area where the Intel MIC solutions may/may not get more traction. As I said, above. Look for companies with Linux "back end" cluster processing that consumes large amounts of x86 processor time. If any of them already have it and are not looking at this they are missing the boat.

For the ones that have already heavily invested the OpenCL and/or CUDA infrastructure, I don't t see them changing course in the near term.







How many KC or 50-core card cards do you believe could be placed in a 1P vs. 2P vs. 4P vs. 8P vs. 12P system

'P' meaning packages? You can probably stop at 2P for workstations. If one card is about 250W and there is also a 60-200W GPU for display driving then the addtional 180-300W for the CPU packages will top out most workstations. Besides if the 50 card gets traction then two 50s if better than 8P or 12P. The cards are adding in chunks an order of magnitude higher.

Intel did a demo with mutliple cards
"...
In one test, Colfax took one of its CXT8000 servers with two Intel Xeon X5690 chips (six cores running at 3.46GHz) and slapped in 24GB of memory and eight of the Knights Ferry coprocessors with the chips running at 1.2GHz. Using the Larrabee 1.6.197 kernel driver (see, it really is a Larrabee GPU), this 4U rack server was able to deliver 7.4 teraflops running the aforementioned SGEMM sorting benchmark. This was using alpha levels of future compilers and drivers from Intel. ... "
http://www.theregister.co.uk/2011/06/20/intel_mic_knights_update/page2.html

The point is the mate 3.4GHz cores to the 1.2GHz ones. Parallel jobs 1.2GHz. Scale jobs 3.4GHz. If you try to use 4 and 12 package set ups all you are doing is killing off the top end scalar speed and soaking up substantial power that could be used to drive the PCI-e cards.

If can manage to get sustained 600-900 GFlops out of one of these cards (not some theoretical peak) there is plenty of serial work for the 1-2 package system to do in trying to keep that throughput up (copying raw data in and copying finished/polished answers out).

I don't think a product coming out in late 2012 is going to be oriented to Xeon 5600 or Xeon 7500 units though. Knights Ferry is the current SDK development card. Maximizing the interconnect speed between Knights Cross and the host processor is going to be very important (data needs to be shuffled in/out). I think that means a PCI-e v3.0 based solution. Otherwise run the risk of 1TFlops being far more a peak number than a sustained number. Sustained numbers tend to win more in a competitive market.


Would I be correct in also assuming that you would recommend just using one GP GPU and saving the other slots for KC or 50-core card if the software that I use can take advantage of them?

Even Nvidia is moving to two card setups.

"NVIDIA graphics solutions certified for accelerating the new Adobe Creative Suite 6 include:

Desktop Workstation:
... Quadro 2000 + Tesla C2075 (NVIDIA Maximus) ... "
http://news.creativecow.net/story/868501


Does this mean that it's your belief that each KC or 50-core card will be priced in the $3-4K range; if not, what range for each?

Closer to the $3-4K than the $8-10K range. There is a tension where Intel will charge enough not to cripple their E5 4000 and whatever follow on to the Xeon 7000 series they have. They are different targeted workloads, but I think they will want to minimize the cannibalization.


Will either card run on Westmere systems?

Run perhaps. Get good sustained throughput results using PCI-e v2.0? No. I'd be surprised if that config is on the officially supported list.
 
That's not really how it works. The Mac Pro is a continuing investment. They have to market, they have to do software support, they have to stock it, they have to dedicate manufacturing resources for it.

Yes, that really is how it works. The above somehow ignores that the Mac Pros sold at their current pricing are profitable. If they continue to sell over the next 4-6 months at those prices even in decreasing numbers they are still profitable. Those profits will pay off much of the costs you are outlining with enough left over to have effectively zero impact on Apple's (and likely the whole Mac divisions) operating margins.


The software support is present whether you sell Mac Pros or not. Mac OS X 10.8 , 10.9 , and probably 10.10 are already penciled in for the Mac Pro where they stop selling now or 6 months from now. If anything it is easier to cover that already committed to cost earlier if continue to sell the box a bit longer.


You can't just make an initial investment and call the rest pure profit.

That's not what I said. I was stating the ongoing costs are relatively low for a product. Milking a cash cow costs money, but the margins generally are high; not maximal .


I kind of agree with this... The problem is I think the Mac Pro has hit a coasting wall. With Thunderbolt and Sandy Bridge, Apple has to make tough choices and can't coast.

Of course they can over the short term. TB won't hit full stride until about a year from now. The number of SB machines that will get bough over the next 4 months is relatively small.

The core issue is that for the following to scenarios.

Scenario 1 : wait for all of new major components to become available in volume and then ship.

outside observables : no announcements. product sold at current pricing


Scenario 2 : decide late 2011 to cancel June/July 2012 with a 3 month "window for folks to do last set of acquisitions" and adjust supply chain accordingy.

outside observables: no announcement till June/July. Product sold at current pricing.


There is no difference from the outside. No announcement doesn't put you in Scenario 1 with much higher probability. They didn't have to cancel earlier. There is no huge driver to announce that.


In addition, there is a "why do we care?" attitude. Every engineer, qa person, software developer, and salesman supporting a $7k Mac Pro for a small audience is a person that could be elsewhere in the company. *cough*iOS*cough*iPhone*cough*iPad*cough*

It isn't about iOS. There are numerous Mac models variants that Apple could work on that can potentially achieve higher growth. Note that the rest of Mac line up has had double digit growth. There is zero need to look at iOS devices for other projects that could sustain Mac growth for those engineers.


Quite frankly, if the Mac Pro keeps loosing users, it's not sustainable. And if the price keeps pushing up, it's going to lose users.

A completely moot point if Apple has already decided to terminate the Mac Pro. termination means the number of users buying is going to drop to zero. That the number is dropping is one of, if not the primary, reason the model would get dropped. A strategy that were that number gently drops to zero, is fine if that is the chosen direction.

There is no step function to the number of buyers here. The number isn't going to instantanously drop to zero once HP/Dell/Lenovo/etc start shipping. It will be lower but not zero.


This is more so at odds with the scenario where coming out with a new direct replacement model. The problem is that some issues ( parts, driver, and/or software available is the primary blocker) that run contrary to the strategy. Not really a big issue over a 3-4 year horizon. It is OK to drop into local minimums as long as get to higher maximums later. Apple has enough cash coming in and stashed away that riding out a local bump in the road is nothing to panic over to throw long standing (and successful) corporate policy out the window for some short term, transient gain.

Understood. But the key question is: Does Apple care?

It has nothing to do with care and much to do with running a business that is trying to track profitable and growing markets.


. But if Apple lost the users looking for a 12 core machine, is that going to really matter to them?

It does if there are a substantive application software base that takes advantage of 12 core machines. If a large number of app vendors are not going to write such apps then ..... no it really doesn't matter because they is little to no value proposition in selling a 12 core box. If there is a high value proposition to a growing market then yes it is going to matter.



It's a matter of triage. Either you lose the lower end users who are mad about shifting Xeon prices and are going for i7 towers, or you lose 12 core users to Windows. Who do you think makes Apple more money?

Apple left the 'discount mini-tower' folks behind many years ago. Between cutting off the "entry to mid range Mac Pro" and "everyone else in Mac Pro mid-upper single + dual", I strongly suspect that the latter, not the former, actually make Apple more money. A dual package box with a single E5 could snare fair large percentage of the upper half of the single package users if priced well.

It is chasing after the "GHz" junkies that is the highly questionable market for the Mac Pro. That has a high fraction of those "I'd rather have an overclocked mini-tower anyway" folks who really aren't highly aligned Mac Pro customers in the first place.

Apple can make a much higher fraction of them happier with E5 1620's ( lowest price , high GHz ) option. But if they won't find value in that I can't see perverting the whole line up to make them happy. Those left are just primarily interested in inflecting collateral damage on the iMacs and minis.


Software that is grossly single threaded constrained is not the future of the Mac Pro. If Apple cuts those folks loose I think that is better move rather than betting the farm on them. There is far more differentiation Apple can do with a dual package box from the rest of the Mac line up Apple can do that just with the single one. Apple can fill the price gap with a "pro" iMac. ( high gamut screen , better cooling , perhaps Xeon E3 with full 20 PCI-e lanes for better TB throughput and better accesibiity like HP Z1 ) .

Ideally they could do both an i7 tower and a DP Xeon tower but I just don't see that in the cards.

An i7 tower doesn't buy them anything.
If they use i7 3900 series it will cost just as much and arrive with approximate same update rate since those chips are coupled to the Xeon E5 release cycle.

If they use mainstream i7 chips then folks will either howl that should be priced to maximally cannibalize the iMac or wail about even higher Apple tax if price segmented above the iMacs. Neither, one of those does Apple much good.

Xeon E3 would put them on the mainstream i7 update cycle if that is what primarily worried about and with easy integration with Thunderbolt design constraints. They have to limbo very close to iMac price zone though (if not $100-200 into it.) .


Dual E5's have two big upsides in aligning with rest of Mac line up.

First, it makes it much easier to embedd a GPU onto the motherboard even if Xeon E5's don't do that in the immediate future. It makes putting TB on the Mac Pro as straight forward as an iMac. In fact could use same componets. In a two package set up there are plenty of PCI-e lanes to go around. ( A version sold with one CPU socket open would be an odd ball that would loose the capability, but that's OK).

Second, again related to the PCI-e lane budget, it makes for a better high computational PCI-e box. Multiple 16x PCI-e cards with plenty lanes left over for 10GbE , TB , and high throughput SATA.



If Apple kills the Mac Pro and doesn't have a replacement tower, I don't think there is going to be a workstation iMac. The existing lines are going to be what we get.

That's because you don't want to kill off the low end single package model. If they do then there is room for one.


I think the Mac Pro market is a market Apple would like to continue to be a part of, but unlike HP, they built their entire tower market on the Xeon, and it's biting them in the ass.

HP with their 5% margin is better off with Macs with their 30% margin. Apple go bit in the ass??? Really? On what significant business metric?
If some customers are piling into a low margin business there is no good reason for Apple to blindly chase after them. It isn't helping HP's PC division to do that. In fact, they almost go spun out purely because their cross line-up margins are so low.


The Apple of today just doesn't have the attention span for that sort of multi tower market, profits aside. Something is going to give somewhere.

It isn't attention span as much as growth. If Apple hits the wall on expanding the Mac market share perhaps they will reverse course. For the moment dropping the Mac Pro probably wouldn't drop Apple out of high single or even double digit growth.
 
Exactly, this is just information we don't have, but Apple probably puts significant market research into. So, their actions likely give us the "correct" choice, especially given their current success.

It is more than a bit noisy, but there is some publicly accessible data.

http://update.omnigroup.com/

It is biased by those who actually do look for updates for their Omniware software but better than nothing. :) Flipping the the "Hardware" and "Graphics" set of charts ( "drop down" menu that defaults to Operating system). Can pull up three very interesting charts.

1. "Graphics" -> Video Adapter Memory
2. "Hardware" -> "CPU count "
3. "Hardware" -> "CPU subtype"

From 1, can see that graphics memory is relatively small which puts a cap on Mac Pro percentages since their graphics cards tend to run larger. [ need that because next two have much noise in CPUs. ]

From 2, if accurate , can see that at least 1.1% of folks are running hackintoshes. ( 4x4 and 6x4 ??? cores x sockets I presume are clearly hackintoshes ). The quad and 4x2 ratio isn't just Mac Pros, but suggestive.

From 3, [ weird because somewhat no consistent with CPU count] pegs the explicitly tagged as Xeons at around 4%. 6 core count pretty low.


But with the dual sockets come the costs of more power consumption and dual processor boards, which mean that $300 savings between the processors for the 2x2630 and the 2650 is eaten away.

But push come to shove could put a single 130-150W offering in a dual set up ( construct a Heatsink that covers both slots to make up the difference) and leave the second DIMM banks empty.

Can still offer at the that sky high price. I think the major market problem is the sky high price relative to 4 core offering that can clock just as high for substantially less.

It could certainly be an option, and it provides people a natural upgrade path.
 
It could certainly be an option, and it provides people a natural upgrade path.

It isn't exactly an upgrade path in the normal sense of the usage. Upgrade typically means "more expensive with more functionality with perceived increased value". The problem here is that a dual package E5 2620 and 2630 boxes will cost less. Then you'd hit a price increase to go "single package" then there would be the higher priced dual packages above that. That is going to have marketing problems. [ It does fit the pricing progression when stacked on top of other core limited 1600 models in a single only box. However, that box is kneecapped on I/O. ]



It is a "value" increase if someone put a very high value on GHz. However, oddly enough, there seems to be a significantly high overlap between those who have high GHz values and those who are more price sensitive. High number of folks that grumble about greater than $3K pricing and lack of GHz delivered in the $2-3K price points. Those folks are still going to bolt to overclocked Windows boxes.

IMHO, it would be far better to keep the basic CPU/DIMM tray design. One root cause problem with the design is that the tray to too small (for substantially more DIMMs slots). If need to tweak the tray to get 80 (or 80-16 if embed mobile GPU on tray ) PCI-e lanes off the tray for the E5 anyway (i.e., the socket on the edge of the tray needs to grow wider), then one solution is to make the tray wider (deeper as oriented inside the MP case) .

Two upsides. With 80 lanes can support three or four 16x PCI-e slots with dual package tray inserted. May not be able to pack 4 200W cards in case, but when there are less power hungry computational cards out there (e.g., 120W a card instead of 220W ). For example, on the motherboard: an embedded GPU , 4x routed to a TB controller, 3 16x sockets , and an 8x socket (for external highspeed I/O SAS/10GbE/FiberChannel). [ the single CPU socket version would drop the embedded GPU because would loose those lanes. ]

Second upside is that should be able to fit two banks of 8 on the card. For example (looking down from above: 'D' being DIMM slot space , 'I' being I/O chipset space , '-' being misc circuitry , and 'C' 2011 socket space )

- DDDD DDDD - I - - - C C C C - -
- - C C C C - - - I - DDDD DDDD -

The single package tray could then look like

- DDDD DDDD - - - I - P P P - - -
- C C C C C C C C - I - - - - - - - -

[ the 2011 socket is not bigger, but heat sink is longer/bigger. ]
where 'P' is extra PCI-e switches where the PCI-e lanes are expanded a bit. Not out to 4 x16 , but something closer to the current 16,16,4,4 set up.
If there is Thunderbolt then on of the 4 is shared with Thunderbolt. There would be some "dead" PCI-e pins coming off the tray for the diminished number of active PCI-e lanes available, but the overall form factor is reusable.

The cubic volume of the overall Mac Pro case doesn't have to increase that much if just shrink the height a bit to cover the increased depth. Nice side effect of that is that can make it rack mountable in horizontal position.

The current Mac Pro's width and depth is what kneecaps the number of DIMM slots. That can change without necessarily moving away from the CPU/DIMM tray design. You still retain the upsides of have the two submodels share a very high number of components and costs.

Using the E5 1600 series, in particular the 1620, would be for more effective in chasing the high GHz but cost sensitive userbase. Some will still bolt for the sub $2K price zone, but that isn't a new issue nor is it solved by going single package only (1600 or 2600 ). Only need to pull down more from the over $3.5K zone to balance the losses. Likewise, the dual packages need to pull in more folks with high I/O and highly parallel workloads. Again, this not really a new problem, but have better infrastructure that offers value in those areas.


I don't think that more PCI-e slots (or lack of legacy PCI slots ) is a huge handicap for the dual package models. DIMMs slots is probably a bigger issue, but that is actually present in both single and dual models. Likewise expanding the power supply and heat dissipation in the PCI-e slots' thermal zone is a single and dual model issue.

Apple may have been trying in part to segment the models on DIMM slots but at this point PCI-e lanes is a better tool. If you go single package then going to loose PCI-e lanes (and possibly Thunderbolt). It is a nice value proposition segmentation barrier because you actually do. It is not particularly artificial (except perhaps the TB part. However, single package does make it a kludge to implement.).

If the Mac Pro has to survive in the over $2K price zone then dropping either "half" , single or double, is not really a good idea.

I suspect the hidden motivation behind some folks pushing the single package agenda is that somehow that sets the ground work for going to 'war' against the iMac. "Don't need dual packages" will be followed by "don't need 40 PCI-e lanes" (PCI-e expander switches are great) , "don't need ECC" , "don't need dual GbE" , ........


I don't see how Apple is going to be motivated to enter that 'war'. A path with less resistance would require a bigger push across the line up by moving the mini , iMac , and Mac Pro all down $100-200 over several years. That could allow the entry Mac Pro back into the sub $2K zone. If the overall PC market keeps moving down Apple may have to drop down some in up coming years. The individual Mac submarkets though probably don't have that kind if juice.
